Differential binomial
From Encyclopedia of Mathematics
An expression of the type
 |
where 
and 
are real numbers, while 
, 
and 
are rational numbers. The indefinite integral of a differential binomial,
 |
is reduced to an integral of rational functions if at least one of the numbers 
, 
and 
is an integer. In all other cases, the integral of a differential binomial cannot be expressed by elementary functions (P.L. Chebyshev, 1853).
Comments
The statement on the reduction to an integral of rational functions is called the Chebyshev theorem on the integration of binomial differentials.
